Today is the 65th anniversary of Nagasaki bomb blast. There has been 2053 nuclear detonations in the world from 1945 to 1998 and only two were act of war (Hiroshima & Nagasaki). Consider what the impact of the two detonations had over the rest of the world and the world would be destroyed if say one fifth of all those bombs detonated were used to kill each other.
Here is an animated map by Japanese artist Isao Hashimoto showing the test sites and originator countries of the 2,053 nuclear explosions during the period 1945-1998 (via Boing-Boing):
Some interesting facts:
Explosions by countries - USA 1032 (including Hiroshima & Nagasaki), USSR 715, France 210, UK 45, China 45, India 4, Pakistan 2.
The explosions peaked during the 1960s and gradually slowed down in the 1990s.
I wonder what permanent damages the holed up test sites have done to the world?
